New semiconducting ligands reach 25% solar cell power conversion

WEST LAFAYETTE, Ind. – Purdue University researchers have created new, multifunctional ligands that improve the charge transfer, power conversion capability and long-term stability of perovskite solar cells.

Perovskite is a material that can be formed from different elements to have a variety of electrical, optical and physical characteristics. Perovskite can be manufactured as solar cells with simple techniques similar to printing newspapers; the techniques cost less and use less energy than those used to produce traditional silicon cells. Perovskite solar panels are also much thinner and lighter than silicon panels, making the transportation and installation cost lower. They can be made lightweight and mechanically flexible and portable. But Letian Dou, the Charles Davidson Associate Professor of Chemical Engineering in the Davidson School of Chemical Engineering, said perovskite solar cells have traits that limit their effectiveness.

Highway technology

 Highway technology

New technology that monitors commercial vehicles will improve safety for local residents and drivers on Highway 5A.

Weigh-in-motion and automatic vehicle-identification systems will monitor commercial vehicles at highway speeds using sensors built into and above the highway. The sensors will measure real-time safety and vehicle data, such as weight, height and tire conditions, and compare the data against enforced standards.

  

Commercial vehicle data will be relayed directly to mobile Commercial Vehicle Safety and Enforcement officers in the area, enabling more efficient intervention and enforcement of safety standards.

Quick Facts:

• The new virtual system on Highway 5A will provide information about all commercial vehicles that pass whether they are enrolled in the Weigh2Go program or not.
• Known collectively as Weigh2GoBC, the ministry has established a network of 12 weigh-in-motion and automatic vehicle-identification technologies that check vehicle safety compliance at highway speed.
• Carriers registered with Weigh2GoBC receive transponders that allow compliant vehicles to bypass inspection stations, saving time and fuel, and reducing greenhouse gas emissions.

Medical Science

 

            The key to understanding how the most aggressive lymphomas arise and resist current therapies may lie in mutations that disrupt a critical natural selection process among antibody-producing B cells, according to a multi-institutional preclinical study led by Weill Cornell Medicine investigators.

Researchers from HSE University and the Moscow State University of Medicine and Dentistry have developed a machine learning model that can predict the word about to be uttered by a subject based on their neural activity recorded with a small set of minimally invasive electrodes.

                    amfAR, The Foundation for AIDS Research, has awarded Luis J. Montaner, D.V.M., D.Phil., in collaboration with Mohamed Abdel-Mohsen, Ph.D., a Target Grant for $397,663 over two years. Montaner, who leads The Wistar Institute's HIV Research Program, is studying the ability of a type of immune cell known as natural killer (NK) cells to kill HIV-infected cells.

                             The cerebellum is a part of your brain located at the back of your head, just above and behind where your spinal cord connects to your brain itself. Although this part only accounts for 10 per cent of the volume of our brain, the cerebellum contains more brain cells than the rest of our brain and is therefore an important area that we want to map out properly.
